APPARATUS FOR MAKING SULFUROUS ACID.

SPECIFICATION forming part of Letters Patent No. 585,404, dated June 29, 1897.

Application filed July 6, 1896. Serial No. 598,206. (No model.)

. To all whom it may concern.-

Be it known that I, ERNsr PORAK, residing at Kienberg, Bohemia, Austria-Hungary, have invented certain new and useful apparatus for burning sulfur and other materials for the obtaining of sulfurous acid (60,) or similar products, of which the following is a specification.

My invention relates to an apparatus for the production of sulfurous acid (S0,) or other gases used for the saturation of fluids by the combustion of sulfur or other substances, the sulfur and sulfurous acid serving in this case only as an example. The chief object of my combination is to avoid the use of the dear and troublesome air-pumps and compressors, which besides this cause the formation of sulfuric acid, (S0 For this purpose Iproduce a forced circulation of an appropriate fluid, as, for instance, of water. I obtain in this way a sucking-jet which sucks the sulfurous acid or other saturating-gas as it arrives from the combustion apparatus. The tube of the jet reaches into the fluid of said reservoir, and thus the sulfurous acid is at the same time washed and put under pressure by the action of the jet itself, the reservoir being closed. From the top of the reservoir the sulfurous acid is led under the acquired pressure to the place of its destination; and in order that my invention may be particularly described and ascertained reference is hereby made to the accompanying drawings, in which- Figure 1 represents the apparatus in a vertical section, and Fig. 2 the same in a horizontal plan view. Fig. 3 is an axial section of the injector.

The closed reservoir G is filled with an appropriate fluid, preferably with water. From its bottom this fluid is sucked by any appropriate pumping-machine E and is forced through the pipes F, injector F and pipe F back to the same reservoir G, the pipe F preferably reaching into the fluid in G.

A represents a stove or any appropriate apparatus for the production of sulfurous acid or other gases used in the saturation of fluids, such sulfnrous acid or other gases being led through the tubes B G D and the cen-' tral pipe S into the enlarged pipe F The pipe S being surrounded by the jet of fluid which is forced back into G, the sulfurous acid is sucked and ejected into the fluid in G, and being therefore washed and compressed at the same time it can be led through the conduit H j or through other appropriate tubes or apparatuses to the place of its destination or further use. F and D, I provide stoppers 2 2, which can be removed for cleaning purposes.

The characteristic and new feature of my invention is the arrangement of the parts G E F F F G by which I suck the gases from the pipe S and force them to enter into the fluid in G, so that the gas is automatically washed and compressed and can therefore be led through the tube II or by other appropriate conduit to the place of its destination, especially for the purpose of saturating fluids.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is- In combination with the closed reservoir G adapted to contain a suitable fluid, a pipe system F, F F making a circuit which includes the reservoir G,.a pump E for drawing the fluid from G and forcing it through the pipe system back to G again, an apparatus for the production of gas and pipe connections to the pipe F said connections terminating in a nipple whereby the fluid passing around said nipple acts by suction to draw in the gas to the reservoir G where it is washed and compressed, and a discharge-conduit H, j, substantially as described.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
